Spectra Lamp Motion, light, and color — layered into one object. Spectra is a 3-piece 3D printed lamp that plays with transparency and shadow. Its outer shell features flame-like cuts that let the light burst through, revealing a glowing inner core you can print in any color you want.

It’s modular, dramatic, and easy to print — no supports needed. Just swap the inner color and let Spectra adapt to your vibe.

🌈 3-part system: base, shell, and glowing core 🎨 Customize the inner color 🛠️ Support-free, FDM-friendly

HOW TO PRINT: The inner part can be printed in vase mode — I recommend a 0.8 mm line width. The outer part can be printed with default settings, no supports needed — same as the base.
